Water Treatment 

Water treatment is one of the broadest and most critical industrial applications, cutting across nearly every sector of the economy. From municipal utilities and desalination plants to industrial wastewater, power generation, pulp & paper, food & beverage, pharmaceutical, and chemical production, the need for clean, reliable water management solutions continues to grow worldwide. 

At Harris Thermal, we bring over a century of experience in ASME-code pressure vessels, heat exchangers, evaporators, and crystallizers to this mission. Our role is to partner with engineering firms, OEMs, and EPC contractors to deliver custom-engineered equipment that enables advanced water purification, wastewater recovery, zero liquid discharge (ZLD), and ultra-pure water (UPW) systems. 

We understand that water treatment is more than compliance—it’s about safeguarding communities, protecting natural resources, and providing industries with reliable infrastructure to thrive. 

Key Applications and Use Cases 

• Municipal and Potable Water – Delivering safe, reliable drinking water infrastructure through purification and disinfection. 

• Desalination and Brackish Water Treatment – Converting seawater or saline groundwater into usable water in highly corrosive environments. 

• Industrial Process and Wastewater – Managing process streams and ensuring safe discharge for industries such as power, pulp & paper, food, chemical, and refining. 

• Zero Liquid Discharge (ZLD) – Using evaporation and crystallization to recover water and capture solids, minimizing waste and enabling sustainability. 

• Ultra-Pure Water (UPW) – Supporting electronics, semiconductor, pharmaceutical, and biotech industries where even trace impurities can impact quality and safety. 

Our Fabrication Capabilities 

Harris Thermal designs and fabricates a wide range of equipment for water treatment applications, including: 

• Falling Film Evaporators – Highly efficient units used for brine concentration, wastewater minimization, and desalination pretreatment. 

• Crystallizers – Engineered for ZLD and high-salinity applications, enabling solids recovery and safe water reuse. 

• Heat Exchangers and Condensers – Thermal efficiency for evaporation, cooling, and energy recovery across treatment systems. 

• Ozone Generation and Disinfection Systems – Including ozone generator housings, contact tanks, diffuser systems, and ozone destruct tanks for safe, effective oxidation. 

• Ultra-Pure Water Equipment – ASME-code vessels, exchangers, and tanks designed for high-purity, contamination-sensitive industries. 

• Process and Mixing Tanks – For chemicals, brine, disinfectants, and treated water storage. 

• Filtration and Separation Vessels – Cyclones, clarifiers, and separators for solids and particulate removal. 

• Scrubber Vessels – To manage off-gassing and emissions during treatment processes. 

• Balance-of-Plant Systems – Integrated solutions including storage, mixing, piping, and auxiliary equipment. 

Materials, Standards and Specialized Expertise 

• Fabrication in stainless steel, duplex, AL-6XN, and high-nickel alloys for corrosive and saline environments. 

• ASME Section VIII Div. 1 certified vessels and TEMA-compliant exchangers. 

• Finishes and fabrication standards suitable for ultra-pure water and contamination-sensitive processes. 

• Field-proven experience in harsh marine environments, high-temperature evaporators, and corrosive chemical service.
